About Me:
I am currently an assistant professor in the Department of Nuclear
Plasma and Radiological Engineering (NPRE) at the University of Illinois
at Urbana Champaign (UIUC). I earned my Ph. D degree from Southampton
University, UK
in 2001 and worked in the Department of Nuclear Engineering and the
Department of Radiology at the University
of Michigan before
joining UIUC.
Research Interests:
Over the past few years, I have been working on a variety of
radiation sensors for both imaging and spectroscopy applications. My
current research interests are centered on
the following areas:
· Ultra-high
resolution nuclear imaging systems for biomedical imaging applications.
This project is for developing an ultra-high resolution Single Photon
Emission Microscope (SPEM) system that offers a sub-hundred micron resolution
for in vivo imaging of mouse brain. We are currently working with
researchers at the University
of Chicago for developing
a full-scale SPEM system that incorporates multiple camera heads and is
integrated with an X-ray CT
system.
· Multi-modality
imaging systems for small animal imaging. This effort is for combining nuclear
imaging techniques with other non-ionizing imaging techniques such as X-ray CT, MRI
and ultra-sound systems.
· Novel
imaging sensors based on room temperature semiconductor materials. We are
currently developing high resolution energy-resolved photon counting
detector that consists of a custom-developed ASIC and pixilated
semiconductor detectors.
